Simulation of File Arrivals and Departures on Buffer sizing in Access Routers

Most of the contemporary systems assumes that all the flow of packets are same and requires O(1) buffer size for transferring packets in a network. This leads to more buffer size even for short flow of packets also, which wastes the buffer size. To overcome this problem, this paper proposes a new technique which uses different buffer sizes based on the packet flows. For long packet flows longer size buffers are used, for short packet flows tiny size buffers are sufficient and for mixed packet flows medium size buffers are used. This paper also presents an approach for increasing the link utilization based on maximum window size.
